SEPARATION OF NONSPHERICAL PARTICLES IN A HYDROCYCLONE

On the basis of hydrodynamic equations, the structure of the fl ow of a suspension in a hydrocyclone and the separation of isothermal nonspherical particles in it were investigated numerically. A mathematical model is proposed for calculating the separation parameters of the indicated particles and their concentration fi eld. It is shown that the most marked dependence of the separation parameters of suspension particles on their shape is characteristic of the particles whose sizes fall within the range 10 < dp < 50 μm and that the separation of such particles should be conducted taking into account the possible deviation of their shape from the spherical one.
